Update sqlite_sequence on ALTER TABLE ... RENAME TO

[kumarUjjawal]

Description

Fixes ALTER TABLE ... RENAME TO for AUTOINCREMENT tables so that sqlite_sequence is updated in place during rename.

Changes:

• Update the ALTER TABLE rename translation path to rewrite
  sqlite_sequence.name from old table name to new table name.
• Keep behavior consistent with existing MVCC update patterns.
• Add regression test autoinc-rename-table-updates-sequence-entry in
  testing/runner/tests/autoincr.sqltest.

Motivation and context

Issue #5129 reported that after:

1. creating an AUTOINCREMENT table,
2. renaming it via ALTER TABLE ... RENAME TO,
3. querying sqlite_sequence,

the old table name remained, and later inserts created a second row for the new table name.

Closes #5129
